What are voltage modes? While all programmable AC power sources offer AC output mode, some also provide DC output mode. This may be useful for applications where only DC is required to power an EUT. However, a growing number of power related products are coming on the market than can operate from both AC grid […]

What is Voltage Distortion? Voltage distortion occurs when an AC output is purely sinusoidal but has small levels of voltage harmonics in addition to the fundamental sinewave frequency. This low level of voltage distortion is often difficult to see on an oscilloscope and requires a power analyzer or harmonics analyzer to quantify. Distortion is typically […]

What is Load Regulation? Load regulation ensures programmed output voltage remains constant despite load variations It is calculated using the following formula: Where VLmin is the voltage at no load and VLmax is the voltage at maximum rated load. It is typically specified in % of full scale voltage. The lower the load regulation spec […]
